Patent GB-654692-A (GB)
Title: Continuous hydrogenation of unsaturated oils
IPC: C11C3/12
Filed: 1948-03-25
Abstract: An unsaturated oil is continuously partially hydrogenated by passing it at a regulated rate through a confined zone with a catalyst whilst introducing hydrogen into the zone proportionately to the degree of hydrogenation required, the feed ratios of oil and hydrogen being such that they remain in the zone until all the hydrogen is utilized. The catalyst is continuously separated from the product and a major part of it is continuously returned to the zone, the rate of withdrawal of used catalyst equalling the rate and input of fresh catalyst.  The process is applicable to unsaturated higher fatty acids (i.e. containing 8-24 carbon atoms) and their esters, and in an example cottonseed oil is partially hydrogenated.  The input of new catalyst is controlled by a proportionating device and the control may be automatic. Specification 648,995 is referred to.

Title: Method and machine for manufacturing elastic helical conducting cords
IPC: D02G3/32
Filed: 1937-03-30
Abstract: 477,246. Braid; electric cables &c. CONDELEX AKT.-GES. March 30, 1937, No. 9042. Convention date, March 28, 1936. [Class 74 (i)] [Also in Group XXXVI] To produce an elastic helical conductive cord on a braiding-machine, resilient threads 5 are fed under tension parallel to a core but spaced therefrom by the braided covering 3. A second braided covering 4 takes in the threads 5. The core may consist of two insulated conductors 1 with which a textile ' filling 2 is twisted. The threads 5, when not in tension, draw the cord into helical coils. The braiding-machine has the usual arrangement of centre-discs &c., forming two sets of interlacing passages and an additional track consisting of passages 20, switches 21, &c. The rubber threads 5 pass up through tubes 13 forming axles for some of the outer driving pinions, and situated adjacent to the inner track. When the bobbins pass through the tracks 20, the rubber threads are not caught in the cord. They are subsequently cut off and bound round at the places 6 when they come through the surface of the braid. The core is preferably supplied in cut lengths hooked together, the ends 7 being covered with oiled linen. The braid 4 forms a continuous covering over the cut lengths. After the places 6 have been bound, the covering may be cut to release the ends 7. The braid is laid tightly over the ends 7, but in the parts where the rubber threads are laid in the braid is looser, being taken up over a wire extending into the braiding eye. When tight braiding is required, this wire is withdrawn. The complete cord is shaped by being wound on a former after steam treatment.

Patent GB-726250-A (GB)
Title: Process for the production of finely divided oxides
IPC: C01B13/22
Filed: 1953-04-02
Abstract: Finely divided oxides of metals or metalloids are produced by hydrolysis of volatile compounds, <PICT:0726250/III/1> <PICT:0726250/III/2> for example silicon tetrachloride, in a flame wherein gases which burn together to form water, for example hydrogen or methane and oxygen, are mixed homogeneously with the volatile metal or metalloid compound in a quantity sufficient to produce sufficient water for complete hydrolysis of said compound, to form a gaseous and/or vaporous mixture, which is thereafter caused to react in a burner flame.  The oxygen is preferably present in the mixture in stoichiometric quantity with respect to hydrogen or hydrogen-containing gas to produce water; but the proportion of hydrolyzable compound and also of oxygen may be varied to give a product of suitable particle size and activity.  The formation of a deposit of finely divided oxides on the margins of the burner may be prevented by reducing the speed of propagation of the flames in the outflowing gases in the immediate neighbourhood of the opening by means of washing gases such air which flow in a thin layer around the burner mouth, or by mechanical stripping. It is desirable to maintain laminar flow both in the burner tube and in the flames.  A temperature of 900 to 1200 DEG C. preferably 1000 to 1100 DEG C. should be maintained; the hot oxide particles may be quenched by injecting water, preferably of varied particle size into the flame, preferably as closely as possible to the end remote from the burner. The oxide particles are preferably kept in suspension and in relative movement, for example for more than 3 secs., preferably more than 5 secs. until all the particles have coagulated into aerogel form, and only then are separated in cyclones, filters, or the like.  Hydrogen or hydrogen-yielding gas may enter the burner shown in Figs. 1 and 1a through 5 while combustion air or a gas-yielding oxygen flows in through inlet 4 and the compound to be decomposed flows in through inlet 4a together with a carrier gas, preferably air, into a turbulent zone.  The gases then pass through star shaped baffles 7, 7a and emerge at the burner mouth 2.  A washing gas such as air which emerges from an annular slot 10 in the jacket 8 prevents the deposition of a beard of oxide.
